I have 4 sealed factory cases of these. Selling as NEW pairs. Please contact me if you need more or less. The tubes are new and verified as such on an amplitrex AT1000 (sample of 20 all tested 100% gm). These is an early version of the sovtek 6L6GC tube with a bottom disc getter.

Again, notwithstanding the foregoing notice, these tubes satisfy all applicable RoHS material restrictions.

They have a massive double disk foil-type round getter. The owner passed away in 2018. These tubes both test at 98% of scale (new is expected above 80%). Very closely matched.
